Review the controller replacement requirements

To replace the controller module, you must meet certain requirements.

Shut down the impaired controller

Shut down or take over the impaired controller so that the healthy controller continues to serve data from the impaired controller storage.

Replace the controller

Replacing the controller includes removing the impaired controller, moving the FRU components to the replacement controller module, and then installing the replacement controller module in the enclosure.

Restore and verify the system configuration

Verify the low-level system configuration of the replacement controller and reconfigure system settings as necessary.

Recable and give back the controller

Recable the controller and transfer the ownership of storage resources back to the replacement controller.

Complete controller replacement

Verify the LIfs, check cluster health, and return the failed part to NetApp.
